It should also be understood that determining B from a does not mean determining B from a alone, but may be determined from a and/or other information.

In the embodiment of the present invention, the access network may be an access network including a Macro Base Station (Macro Base Station), a micro Base Station (Pico Base Station), a Node B (3G mobile Station), an enhanced Base Station (eNB), a 5G mobile Base Station (gNB), a Home enhanced Base Station (Femto eNB or Home eNode B or Home eNB or HeNB), a relay Station, an access point, an RRU (Remote Radio Unit, Remote Radio module), an RRH (Remote Radio Head), and the like. The terminals (first terminal, second terminal, etc., as described below) are V2X terminals. For example, the device may be a vehicle-mounted terminal, a mobile phone (or a mobile phone), or other devices capable of sending or receiving wireless signals, including user Equipment, a Personal Digital Assistant (PDA), a wireless modem, a wireless communicator, a handheld device, a laptop computer, a cordless phone, a Wireless Local Loop (WLL) station, a CPE (Customer premises Equipment) or a mobile smart hotspot capable of converting mobile signals into WiFi signals, a smart appliance, or other devices capable of autonomously communicating with a mobile communication network without human operation.

Specifically, the embodiment of the invention provides an information processing method, which solves the problem that dangerous situations such as early warning, false alarm, decision errors, error prompt, error downtime and the like may occur in the actual application process of V2X.

As shown in fig. 1, an embodiment of the present invention provides an information processing method, which specifically includes the following steps:

step 11: and receiving first path attribute information sent by a first path side node.

The first road section attribute information is used for indicating a road section attribute of a first road section where the first road side node is located, and the road section attribute is determined based on at least one of height, area and path of the road section. Alternatively, the area information may include latitude and longitude information, and the route information may include a driving direction corresponding to the road segment, a road extending direction, and the like.

Wherein physically isolated different roads within the same V2X communication range (e.g., direct link, coverage area on the order of hundreds of meters) are divided into different road segments and configured with different segment attribute information. For example: the divided road sections are physically isolated, and the vehicles running on different road sections do not have the risk of mutual collision.

Alternatively, different roads located within the same V2X communication range, having the same regional information and different altitude information are divided into different road segments. For example: for roads of viaduct, circular spiral highway, etc., the area information corresponding to some road segments may be the same, but the corresponding altitude information is different, for example, the area information of road a and road B in fig. 2 is the same, but the altitude information is different, then road a and road B are divided into different road segments, or the area information of road C, road D and road E is the same, but the altitude information is different, then road C, road D and road E are divided into different road segments, wherein the altitude information of road a and road C is the same, so that the road a and road C can be divided into the same road segment, and the altitude information of road B and road D can be divided into the same road segment.

If the area information corresponding to the road AB, the road CD, and the road EF in fig. 3 is the same, but the altitude information is different, the road AB, the road CD, and the road EF are divided into different segments.

Alternatively, different roads located within the same V2X communication range, having the same route information and different area information are divided into different road segments. For example: for a road in a "snake" shape, the path information corresponding to a part of the area may be the same, but the area information corresponding to the part of the area may be different, for example, the path information of the curve a, the curve B, and the curve C in fig. 4 (for example, the arrow in fig. 4 indicates the path) is the same, but the area information corresponding to the curve C is different, the road segment where the curve a, the curve B, and the curve C are located may be divided into different road segments, or the path information of the curve D, the curve E, and the curve F in fig. 4 is the same, but the area information corresponding to the curve D, the curve E, and the curve F are different, the road segment where the curve D, the curve E, and the curve F are located may be divided into different road segments.

Alternatively, different roads located within the same V2X communication range, having the same route information and different altitude information are divided into different road segments. For example: for a road in a "snake" shape, the path information corresponding to a part of the area may be the same, but the corresponding altitude information may be different, for example, the path information of the curve a, the curve B, and the curve C in fig. 4 (for example, the arrow in fig. 4 indicates the path) is the same, but the corresponding altitude information is different, the road segment where the curve a, the curve B, and the curve C are located may be divided into different road segments, or the path information of the curve D, the curve E, and the curve F in fig. 4 is the same, but the corresponding altitude information is different, the road segment where the curve D, the curve E, and the curve F are located may be divided into different road segments.

It should be noted that the area information mentioned in the embodiment of the present invention is the same, and may mean that the difference between the longitudes/the difference between the latitudes is within a preset range, and the difference between the area information may mean that the difference between the longitudes exceeds the preset range, or that the difference between the latitudes exceeds the preset range; the height information being the same may mean that a difference between height (or elevation) values is within a preset range, and the height information being different may mean that a difference between height (or elevation) values exceeds the preset range; the path information may be the same, that is, the difference between the path directions is within a preset range, and the path information may be different, that is, the difference between the path directions exceeds the preset range.

It should be further noted that, the above gives examples of the division of different road segments, and besides, the division manner of different road segments may include: the embodiments of the present invention are not limited thereto, and the way of dividing the road into different road segments by at least one of the height information, the area information, and the route information is within the protection scope of the present invention.

Step 12: and setting the first road section attribute information as the road section attribute information corresponding to the first terminal, and sending the road section attribute information corresponding to the first terminal to the outside.

Optionally, in a case that the first terminal is within the communication range of the first road side node, the first terminal may receive the first road segment attribute information of the first road segment where the first road side node is located, set the first road segment attribute information as its own road segment attribute, and send the road segment attribute information to the outside, so that the second terminal that is within the V2X communication range of the first terminal may receive the road segment attribute information corresponding to the first terminal.

Optionally, one or more first road side nodes are set in advance on different road sections, for example: the first road side node may be disposed at an entrance of the corresponding road segment, or at an exit of the corresponding road segment, or at another predetermined position of the corresponding road segment, so that the communication range of the first road side node only covers the corresponding road segment, as follows: the working power of the first road side node may be set to be a predetermined power, where the predetermined power is to enable the communication range of the first road side node to only cover the corresponding road segment, or to enable the communication range of the first road side node to only cover the corresponding road segment in a directional antenna manner, and the like.

Preferably, a first road side node may be set corresponding to a road segment, such as: the first road side node can be arranged at an entrance of a corresponding road section, so that when a first terminal passes through or enters the road section from the entrance, the first road section attribute information sent by the first road side node can be obtained, the setting number of the first road side node can be reduced, and the node setting cost is reduced.

Specifically, when a first terminal passes through an entrance or enters the road segment, the first terminal may receive first road segment attribute information sent by a first road side node at the entrance, and store the first road segment attribute information; therefore, the first terminal can send the corresponding road section attribute information to the outside through the stored first road section attribute information in the process that the first terminal is located in the first road section.

Further, after storing the first path segment attribute information, if receiving third path segment attribute information sent by the first path side node, updating to store the third path segment attribute information; and the first road side node sending the third road section attribute information and the first road side node sending the first road section attribute information are first road side nodes corresponding to different road sections.

For example: when the first terminal reaches the third route segment through the first route segment, the third route segment attribute information sent by the first route side node at the entrance of the third route segment can be received, and at the moment, the first terminal can update the first route segment attribute information stored by the first terminal into the third route segment attribute information.

In this way, the first terminal located in the communication range of the first road-side node may receive the first link attribute information sent by the first road-side node, and in a case where the first terminal is an on-vehicle terminal, that is, in a case where the vehicle enters the communication range of the first road-side node, or in a case where the vehicle is located in the communication range of the first road-side node of the first road (for example, the vehicle passes through the first road segment or passes through the first road segment), the vehicle may receive the first link attribute information sent by the first road-side node, and since the communication coverage area of the first road-side node only includes the road segment where the vehicle is located and does not include other road segments, it is ensured that the vehicle traveling on the local road segment can receive the link attribute information of the road segment, and it is ensured that the vehicle traveling on other road segments cannot receive the link attribute information of the road segment.

In the scheme of the embodiment of the invention, based on that different physically isolated roads in the same V2X communication range are divided into different road segments and different road segment attribute information is configured, the first terminal can receive the first road segment attribute information of the first road segment where the first terminal is located through the first road side node, so that under the condition of ensuring information safety, sharing of the road segment attribute information determined based on at least one piece of information such as height, area and path in the V2X technology is realized, and further, the problem of dangerous conditions such as early warning and false alarm, decision errors, error prompt, error downtime and the like possibly caused by the fact that the terminal is located on the road segments with different heights, different areas or different paths in the current V2X practical application can be avoided.

Optionally, the first terminal may send a first Message indicating the location information of the first terminal to the outside in a broadcast manner, where the first Message may be a Basic Safety Message (BSM); the BSM includes a first field dedicated to indicate the link attribute information corresponding to the first terminal, or a specific value of an existing second field in the BSM is used to indicate the link attribute information corresponding to the first terminal.

For example: a first field specially used for indicating the link attribute information corresponding to the first terminal may be newly added in the BSM, and the first field may indicate the link attribute information corresponding to the first terminal in an explicit or implicit manner; or, the segment attribute information corresponding to the first terminal may also be indicated by a specific value of an existing field of the BSM, for example: the present invention may use the existing height field Elevation (-4096.61439) in the BSM, and use a value 1 to represent the road segment 1, and a value 2 to represent the road segment 2, etc., which is not limited in this embodiment of the present invention.

Of course, in the embodiment of the present invention, the first message for indicating the location information of the first terminal may be sent out in a broadcast manner, and may also be sent in a unicast manner, a multicast manner, and the like, which is not limited in this embodiment of the present invention.

For example: the height information, the second bit indication area information, and the third bit indication path information may be indicated by the first bit of the link number, and the sequence of indicating the height information, the area information, and the path information in the link number may be any predetermined sequence, which is not limited in the embodiments of the present invention.

For another example: the road type may be indicated by 1 bit, for example, 1 bit indicates that the current road type is a road type with different height information of different road segments, or the current road type is a road type with different area information of different road segments, or the current road type is a road type with different path types of different road segments; further, when the current road type is a road type with different height information of different road sections, indicating the height information of the current road section by 1 bit (such as quantized height information or the grade of the height information corresponding to the current road section); indicating the area information of the current road section by 1 bit under the condition that the current road type is a road type with different area information of different road sections; in the case that the current road type is a road type with a different route type of a different road segment, the route information of the current road segment is indicated by 1 bit, and the like, which is not limited in the embodiments of the present invention.

Alternatively, when the vehicle runs through or stops in the communication range of the first road side node, the link number and other associated information sent by the first road side node are received, and are used as the link number information and other associated information of the host vehicle, and then when the vehicle sends a V2X message to the outside, the link number information and other associated information of the host vehicle are sent to the outside, wherein the link number may be explicitly indicated (for example, the link number is indicated by a dedicated field of the BSM), and the position information associated with the link number may also be filled in the message sent by the vehicle (for example, the link number is indicated by a specific value of an existing field of the BSM).

Optionally, the method further comprises:

Optionally, the first segment attribute information and the second segment attribute information are different, and may refer to at least one of that the height information indicated by the first segment attribute information is different from the height information indicated by the second segment attribute information, that the area information indicated by the first segment attribute information is different from the area information indicated by the second segment attribute information, and that the path information indicated by the first segment attribute information is different from the path information indicated by the second segment attribute information.

For example: the height information indicated by the first road segment attribute information is different from the height information indicated by the second road segment attribute information, and may be that, if the first terminal is located on the road a and the second terminal is located on the road B in fig. 2, that is, the first terminal and the second terminal are located on different roads with different heights and do not have the condition of triggering the forward collision warning, the first terminal may ignore the second road segment attribute information sent by the second terminal and do not need to perform relevant processing such as collision warning application.

Optionally, when the first road segment attribute information and the second road segment attribute information are the same, that is, when it is determined that the first terminal (for example, a vehicle-mounted terminal of the first vehicle) and the second terminal (for example, a second vehicle-mounted terminal of the second vehicle) are located on the same road segment, relevant processing such as collision warning application is executed, so as to avoid occurrence of a safety accident.

Optionally, the method further comprises:

receiving a cancel command sent by a second road side node;

Optionally, the second road side node is disposed at an intersection of a first road region including physically separated different roads within the same V2X communication range and a second road region not including physically separated different roads within the same V2X communication range.

For example: the second road side node can send a message to the outside wirelessly by adopting a preset power or a directional antenna mode, and the message content is to inform the vehicle to cancel the road section number (namely, a cancellation command). And when the vehicle runs through or stops in the communication range of the second road side node, receiving the message sent by the second road side node, setting the link attribute information of the link where the vehicle is located as invalid, and when the vehicle sends the V2X message to the outside after the link attribute information is already set as invalid, not sending the link attribute information of the link where the vehicle is located to the outside.

In this embodiment, on the basis that at least two first road side nodes in the first road area are used for sending the road segment attribute information to the outside, a second road side node may be set at an exit position of the first road area, and is used for sending a cancel command to the outside to instruct the first terminal to cancel setting the first road segment attribute information as its own road segment attribute, so as to cancel sending the road segment attribute information to the outside; or the cancel command is directly used for instructing the first terminal to cancel the outward sending of the road section attribute information.

Therefore, the number of the nodes on the first road side can be reduced for the second road areas of different physically isolated roads which are not located in the same V2X communication range, and dangerous situations such as early warning, false decision, false prompt, false downtime and the like which may occur after the first terminal passes through the first road area and reaches the second road area can be avoided.

Alternatively, the first road side node and the second road side node may be the same device or different devices, and when the first road side node and the second road side node are the same device, the function performed between the road side node disposed in the first road area and the road side node disposed at the intersection of the first road area and the second road area is different.

Fig. 5 is a schematic diagram illustrating information interaction between a terminal and a first road side node and between terminals. Referring to fig. 2, road a and road C correspond to segment 1, road B and road E correspond to segment 2, and road F corresponds to segment 3.

A terminal (such as a vehicle) located on the road section 1 receives the road section attribute information of the current road section sent by the first road side node 1, and determines the road section attribute information of the vehicle according to the road section attribute information sent by the first road side node 1; and then, sending the road section attribute information of the vehicle to the surrounding environment (such as to a terminal in the surrounding environment), and correspondingly acquiring the road section attribute information corresponding to other terminals (such as other vehicles) from the surrounding environment, so that a relevant strategy can be formulated according to the road section attribute information of the vehicle, namely the road section attribute information corresponding to other vehicles.

A terminal (such as a vehicle) located on the road section 2 receives the road section attribute information of the current road section sent by the first road side node 2, and determines the road section attribute information of the vehicle according to the road section attribute information sent by the first road side node 2; and then, sending the road section attribute information of the vehicle to the surrounding environment (such as to a terminal in the surrounding environment), and correspondingly acquiring the road section attribute information corresponding to other terminals (such as other vehicles) from the surrounding environment, so that a relevant strategy can be formulated according to the road section attribute information of the vehicle, namely the road section attribute information corresponding to other vehicles.

A terminal (such as a vehicle) located on the road section 3, receiving the road section attribute information of the current road section sent by the first road side node 3, and determining the road section attribute information of the vehicle according to the road section attribute information sent by the first road side node 3; and then, sending the road section attribute information of the vehicle to the surrounding environment (such as to a terminal in the surrounding environment), and correspondingly acquiring the road section attribute information corresponding to other terminals (such as other vehicles) from the surrounding environment, so that a relevant strategy can be formulated according to the road section attribute information of the vehicle, namely the road section attribute information corresponding to other vehicles.

The following describes the information processing method with reference to specific examples:

the first embodiment is as follows:

as shown in fig. 6, the vehicle a is located on the road segment 1, the road segment attribute information of the corresponding road segment is obtained through the node 2 (if the height level of the vehicle a is 1), the vehicle B is located on the road segment 1, the link attribute information of the corresponding link is obtained by the node 1 (e.g., the vehicle B is located at the altitude level 1), the vehicle C is obtained by the node 3 (e.g., the vehicle C is driving from the link 2 to the link 3, and is located at the altitude level between the altitude level 2 and the altitude level 3), the vehicle D is located at the link 3, the node 4 obtains the link attribute information of the corresponding link (for example, the height level of the vehicle D is 3), the vehicle A, B, C, D sends the link attribute information of the link where the vehicle is located to the surrounding environment, and meanwhile, acquiring the road section attribute information sent by other vehicles except the own vehicle in the surrounding environment.

For the vehicle a and the vehicle C, under the condition that there is no interaction of the road section attribute information between the vehicle a and the vehicle C, the vehicle a and the vehicle C meet the condition of the forward collision warning through the judgment of the position information, but the actual vehicle a and the vehicle C are located in different road sections, and relevant processing such as collision warning application and the like is not required.

In the embodiment of the invention, because the vehicle A and the vehicle C can interact with the respective road section attribute information, the fact that the vehicle A and the vehicle C are in different height levels can be known according to the height level information, namely the vehicle A and the vehicle C are located in different road sections, and therefore, the forward collision early warning can not be triggered, and the possibility of misinformation is avoided.

Example two:

as shown in fig. 7, the vehicle a is located on the road segment 2, the road segment attribute information of the corresponding road segment is obtained through the node 2 (if the vehicle a is located at the height level of 2), the vehicle B is located on the road segment 1, the link attribute information of the corresponding link is obtained by the node 1 (e.g., the vehicle B is located at the altitude level 1), the vehicle C is obtained by the node 3 (e.g., the vehicle C is driving from the link 2 to the link 3, and is located at the altitude level between the altitude level 2 and the altitude level 3), the vehicle D is located at the link 3, the node 4 obtains the link attribute information of the corresponding link (for example, the height level of the vehicle D is 3), the vehicle A, B, C, D sends the link attribute information of the link where the vehicle is located to the surrounding environment, and meanwhile, acquiring the road section attribute information sent by other vehicles except the own vehicle in the surrounding environment.

For the vehicle A and the vehicle C, the vehicle A and the vehicle C meet the condition of forward collision early warning through position information judgment, the fact that the vehicle A runs from the road section 2 to the road section 3 can be determined according to the driving intention of the vehicle A, and due to the fact that respective road section attribute information can be interacted between the vehicle A and the vehicle C, namely the fact that the vehicle A runs to the road section 3 and is in danger of forward collision with the vehicle C is known through the height grade information of the vehicle A and the vehicle C, the forward collision early warning is triggered at the moment, and therefore the possibility of dangerous accidents is avoided.

For the vehicle B and the vehicle D, under the condition that there is no interaction of the road section attribute information between the vehicle B and the vehicle D, the position information of the vehicle B and the vehicle D is judged by the position information, and the position information of the vehicle B and the vehicle D is coincident, and the vehicle decision system may possibly cause the possibility of downtime due to the position coincidence.

Example three:

in the actual road, there are roads as shown in fig. 8 and 9, where the vehicle a is located on the road segment 1, the node 1 obtains the road segment attribute information of the road segment where the vehicle a is located (e.g., the road segment where the vehicle a is located is level 1), the vehicle B is located on the road segment 2, and the node 2 obtains the road segment attribute information of the road segment where the vehicle B is located (e.g., the road segment where the vehicle B is located is level 2).

For the vehicle a and the vehicle B, under the condition that there is no interaction of the road section attribute information between the vehicle a and the vehicle B, the possibility of determining that the vehicle a and the vehicle B are traveling in the same road section in the opposite direction may be caused due to the existence of the positioning deviation, and further, the false alarm of the early warning mechanism is caused, and the occurrence of a traffic accident is caused.

In the embodiment of the invention, the vehicle a and the vehicle B can send the road section attribute information of the road section where the vehicle a and the vehicle B are located to the surrounding environment, and meanwhile, the road section attribute information sent by other vehicles except the vehicle a in the surrounding environment can be obtained. For the vehicle a and the vehicle B, the respective road section attribute information can be interacted between the vehicle a and the vehicle B, that is, the vehicle a and the vehicle B are in different road section grades through the acquired road section grade judgment, that is, the vehicle a and the vehicle B are in different road sections, and the condition of collision early warning is not met, so that the occurrence of false warning is avoided, and the risks of downtime and false warning due to position coincidence are avoided.

Example four:

in an actual road, there is a spiral road as shown in fig. 10, a part of the road section is not divided into several branches, but a plurality of parts on the road section may overlap on two-dimensional coordinates. Although there are several sections of the spiral road with different elevation information, there is no way to distinguish between different vehicles within the same V2X communication range, and there is a risk of collision. In the embodiment of the present invention, whether a vehicle needs to consider its safety information may be determined by setting a plurality of first road side nodes, according to the link attribute information of the corresponding link sent by the first road side nodes, or according to the number of the first road side nodes through which different vehicles pass.

The manner of determining whether the vehicle needs to consider the safety information of the vehicle according to the link attribute information of the corresponding link sent by the first link side node is similar to that in the above embodiment, and is not described here again. The following description is made for determining whether a vehicle needs to consider its safety information according to the number of a first road side node through which a different vehicle passes:

as shown in fig. 10, vehicle a is between first road side nodes 1, 2, vehicle B is between first road side nodes 4, 5, and vehicle C is between first road side nodes 5, 6, and the two-dimensional coordinates of vehicle a, vehicle B, and vehicle C are all relatively similar. Thus, the vehicle a, the vehicle B, and the vehicle C may broadcast information (such as a node number) of a last first road side node that the vehicle C passes by, that is, when the information of the last first road side node that the vehicle C passes by is performed between the vehicle a, the vehicle B, and the vehicle C, the vehicle a determines that the vehicle a is closer to the vehicle B through the two-dimensional coordinate, but since the number of the last first road side node that the vehicle B passes by is No. 4 and the number of the last first road side node that the vehicle a passes by is No. 1, and they are not adjacent to each other, the vehicle a determines that the vehicle a should not be at a height with the vehicle B, and does not trigger a forward collision warning; vehicle B judges through two-dimensional coordinate that it is nearer with vehicle C, and the serial number of the first road side node that vehicle B passed through at last is No. 4, and the serial number of the first road side node that vehicle C passed through at last is No. 5, and is adjacent between the two, can judge that vehicle B is nearer with vehicle C's distance to vehicle B triggers preceding collision early warning.

In the above embodiment of the present invention, the configuration of the branch segment information of the layered (different heights), the partitioned (different areas), the branch path, and other types of roads is implemented by dividing the physically separated different roads within the same V2X communication range into different road segments and configuring different road segment attribute information, so that when a vehicle passes through the corresponding road segment, the road segment attribute information can be obtained through the first road side node of the corresponding road segment, and is used as the road segment attribute information of the vehicle and is sent to the surrounding environment, and after the vehicle in the surrounding environment receives the road segment attribute information of the vehicle, whether the vehicle is in the same road segment can be determined by determining whether the height, the area, the path, and the like indicated by the road segment attribute information are the same, thereby avoiding the situation of a viaduct, a spiral road, a serpentine road, and the like under the condition of ensuring the information security, In some scenes such as an expressway, due to inaccurate positioning or incapability of acquiring elevation information and the like, dangerous situations such as early warning, false alarm, decision errors, error prompt, error downtime and the like may occur.

The information processing method according to the embodiment of the present invention is introduced from the terminal side, and the information processing method of the first road side node side is further described below.

Specifically, an embodiment of the present invention further provides an information processing method, which is applied to a first road side node, and the method includes:

sending first road section attribute information of a first road section where the first road side node is located outwards; the first road segment attribute information is used for indicating road segment attributes of the first road segment, and the road segment attributes are determined based on at least one of height, area and path of the road segment.

Optionally, the first road side node may send the first road segment attribute information of the first road segment where the first road side node is located to the outside in a broadcast manner, and certainly, a unicast manner, a multicast manner, or a multicast manner may also be used, which is not limited in the embodiment of the present invention.

Alternatively, the area information may include latitude and longitude information, and the route information may include a driving direction corresponding to the road segment, a road extending direction, and the like.

Wherein different physically isolated roads within the same V2X communication range are divided into different road segments and configured with different road segment attributes. For example: the divided road sections are physically isolated, and the vehicles running on different road sections do not have the risk of mutual collision.

Optionally, the physically isolated different roads located within the same V2X communication range are divided into different road segments, which may include: different roads which are located in the same V2X communication range, have the same area information and different height information are divided into different road sections; for example: for roads of viaduct, circular spiral highway, etc., the area information corresponding to some road segments may be the same, but the corresponding altitude information is different, for example, the area information of road a and road B in fig. 2 is the same, but the altitude information is different, then road a and road B are divided into different road segments, or the area information of road C, road D and road E is the same, but the altitude information is different, then road C, road D and road E are divided into different road segments, wherein the altitude information of road a and road C is the same, so that the road a and road C can be divided into the same road segment, and the altitude information of road B and road D can be divided into the same road segment.

Optionally, the physically isolated different roads located within the same V2X communication range are divided into different road segments, which may include: different roads which are located in the same V2X communication range, have the same path information and different area information are divided into different road sections; for example: for a road in a "snake" shape, the path information corresponding to a part of the area may be the same, but the area information corresponding to the part of the area may be different, for example, the path information of the curve a, the curve B, and the curve C in fig. 4 (for example, the arrow in fig. 4 indicates the path) is the same, but the area information corresponding to the curve C is different, the road segment where the curve a, the curve B, and the curve C are located may be divided into different road segments, or the path information of the curve D, the curve E, and the curve F in fig. 4 is the same, but the area information corresponding to the curve D, the curve E, and the curve F are different, the road segment where the curve D, the curve E, and the curve F are located may be divided into different road segments.

Optionally, the physically isolated different roads located within the same V2X communication range are divided into different road segments, which may include: different roads located within the same V2X communication range, having the same route information and different altitude information are divided into different road segments. For example: for a road in a "snake" shape, the path information corresponding to a part of the area may be the same, but the corresponding altitude information may be different, for example, the path information of the curve a, the curve B, and the curve C in fig. 4 (for example, the arrow in fig. 4 indicates the path) is the same, but the corresponding altitude information is different, the road segment where the curve a, the curve B, and the curve C are located may be divided into different road segments, or the path information of the curve D, the curve E, and the curve F in fig. 4 is the same, but the corresponding altitude information is different, the road segment where the curve D, the curve E, and the curve F are located may be divided into different road segments.

Optionally, the sending the first road segment attribute information of the first road segment where the first road side node is located to the outside includes: and sending the first road section attribute information of the first road section where the first road side node is located outwards in a mode of preset power or a directional antenna.

Optionally, one or more first road side nodes are set in advance on different road sections, for example: the first road side node may be disposed at an entrance of the corresponding road segment, or disposed at an exit of the corresponding road segment, or disposed at another predetermined position of the corresponding road segment, so that the communication range of the first road side node only covers the corresponding road segment corresponding to the first road side node.

Specifically, when the first terminal passes through the entrance or enters the road segment, the first road-side node at the entrance may send the first road segment attribute information to the first terminal, and the first terminal may store the first road segment attribute information, so that the first terminal may send the road segment attribute information corresponding to the first terminal to the outside through the stored first road segment attribute information in the process that the first terminal is located in the first road segment.

Further, after the first terminal stores the first segment attribute information, if the first terminal reaches the third segment through the first segment, the third segment attribute information sent by the first segment side node at the entrance of the third segment may be received, and at this time, the first terminal may update the stored first segment attribute information to the third segment attribute information.

In this way, the first road side node may send the first road section attribute information of the first road section where the first road side node is located to the first terminal in the communication range thereof, for example, in a case that the first terminal is a vehicle-mounted terminal, that is, in a case that the vehicle enters the communication range of the first road side node, or in a case that the vehicle is located in the communication range of the first road side node of the first road section (for example, the vehicle passes through the first road section or passes through the first road section), the first road side node may send the first road section attribute information to the vehicle, and since the communication coverage area of the first road side node only includes the road section where the vehicle is located and does not include other road sections, it is ensured that the vehicle traveling on the local road section can receive the road section attribute information of the road section, and it is ensured that the vehicle traveling on other road sections cannot receive the road section attribute information of the road section.

In the scheme of the embodiment of the invention, based on that different physically isolated roads in the same V2X communication range are divided into different road segments and different road segment attribute information is configured, the first road side node sends the first road segment attribute information of the first road segment where the first road side node is located to the first terminal, so that under the condition of ensuring information safety, sharing of the road segment attribute information determined based on at least one piece of information such as height, area, path and the like in the V2X technology is realized, and further, the problem of dangerous conditions such as false warning, wrong decision, wrong prompt, wrong downtime and the like possibly caused by the fact that the terminal is located on the road segments with different heights, different areas or different paths in the current V2X practical application can be avoided.
